In git-format-patch, notes can be appended with the `--notes` option.
However, this must be specified by the user on an
invocation-by-invocation basis. If a user is not careful, it's possible
that they may forget to include it and generate a patch series without
notes.

Teach git-format-patch the `format.notes` config option its value is a
notes ref that will be automatically be appended. The special value of
"standard" can be used to specify the standard notes. This option is
overridable with the `--no-notes` option in case a user wishes not to
append notes.

One thing I'm worried about is that I'm not really sure using "standard"
as the special value is a good idea. Would "auto" be a better special
value?

Use braces on both parts of the "if", if one part needs them.

Thanks, I should've read through the log message more carefully before
sending.

I thought that the style preference in this project is to not use braces
whenever it's unnecessary, even if it's on just one arm of an if-else.

+If the special value of "standard" is specified, then the standard notes
